Monsanto GMO Scientist Fred Perlak discusses disruption, RoundUp and wine | The Vance Crowe Podcast

About this episode

Vance interviews Dr. Fred Perlak — his real-life Monsanto mentor and, by his own account, who would have been his very first podcast guest if the show had existed sooner. Perlak, a career Monsanto scientist and co-developer of BT Cotton, walks through his own career arc: an early love of lab work discovered in an undergraduate independent research program, decades running Monsanto's Hawaii breeding operation and pioneering genetically engineered cotton, and later a difficult transition into "corporate engagement" (public-facing communications work) after his scientific career, where he found the culture's lack of long-term commitment ("we've already gotten the publicity from that one") disappointing compared to the mission-driven research culture under CEO Dick Mahoney. The conversation ranges widely across the mechanics of Roundup/glyphosate (explained via a memorable "highway traffic jam" analogy and a "seven-foot doorway" analogy for how selection, not induced mutation, drives resistance), the economics of technology-fee licensing that reshaped the seed industry, and a candid, hedged answer on the glyphosate–cancer question — Perlak places the risk "between hot tea and bacon," a notably more nuanced answer than Vance says he typically gets from pro-Monsanto sources, followed by his "glass of water" analogy for how doubt is manufactured regardless of actual risk. The episode closes on lighter, personal territory: Perlak's philosophy of "aloha" as authentic self-presentation in public speaking and testimony, his introduction of Vance to wine appreciation and the concept of terroir, and reflections on retirement, reading, and mentorship. Compared to other episodes, this one is unusually institutions/bubbles/craft-heavy and windows-light — it's fundamentally a mentor-mentee retrospective on how a major science-based company builds (and loses) public trust, rather than a story about personal risk-taking or crossing thresholds.

Key moments

• **[00:43:15–00:44:22]** Perlak's explanation of insect-resistance "refuge" strategy — requiring 20% non-BT cotton planting even against sales-team objections — and Monsanto revoking a Georgia legislator's license to buy BT seed for non-compliance, showing genuine scientific discipline enforced against short-term profit incentive.
• **[01:04:16–01:07:28]** Discussion of pre-Roundup farm injuries from combines jamming on weeds, with Perlak's claim that Roundup Ready dramatically reduced farmer hand/finger injuries — an unexpected human-safety angle rarely raised in GMO debates.
• **[01:08:21–01:12:54]** The glyphosate-cancer exchange: Perlak's "between hot tea and bacon" risk framing, followed by his critique of class-action lawsuit economics and comparison to opioid litigation — Vance notes this is the most hedged, least dismissive answer he's heard from a Monsanto-affiliated source.
• **[01:59:03–02:00:47]** Perlak recounts the pivotal mentorship moment on a park bench: warning Vance "you're falling in love with this place... it's not your job to defend this place, it's to answer people's questions" — recontextualizing Vance's entire Monsanto communications career.
• **[02:10:00–02:10:25]** Small human detail: Perlak reveals he secretly paid out-of-pocket for a nicer bottle of wine on a work dinner so it wouldn't show up on the expense report — illustrating his personal generosity and mentorship style outside formal channels.

Notable quotes

“You want to build a doorway that's six foot eleven and just ask people to walk through... eventually you'll find people over seven foot. Building the doorway didn't cause them to be seven foot.”

“If Monsanto caused cancer, it would be a very low probability... he put it in between hot tea and bacon.”

“Imagine this glass is full... look at the glass, look up at your friend, smile, then look back down. Are they gonna drink that water? Hell no.”

“It's not your job to defend this place. Your job is to answer other people's questions.”
